Application filed July 20, 1922. Serial No. *?6379.

To aZZ whom 2'25 may concern: wise formed, this arm beingso shaped Be it known that l, Wiminu l. GERBER, that it may be easily interpcsed l'ietween a citizen of the United States, residing at the oil tube 5 of an automobile engine and Deadwood, in the county of Lawrence and a part spaced from the end of said tube,

a iiltate of South Dakota, have invented cerfor instance one of the timing gears 6- In tain new and useful Improvements in Uilthe present showing, the inner sine oi the Tube Cleaners; and I do declare the followarm i is of substantially conical iorrn at its ing to be a full, clear, and exact description outer end as indicated at 7 so as to be easily of the invention, such as will enable others en 'ageable with the end of the oil tube,

VJ hen its use is needed, in order to the tube, being provided with means to enapply the device, it is simply necessary to gage this part so as to hold the cleaner remove one or the usual. oil pan covers, in place while forcing fluid under pressure whereupon the connection 1 may be ins rttherethrough to clean the tube. ed into the oil pan and positioned between lVith the foregoin g in view, the invention the tube 5 and the timing gear 6 or other de- 39 resides in the novel subject matter hereinsired part. The spring 9 engages this part @5 alter described and. claimed, the description and detachably holds the arm i in proper being supplemented by the accompanying relation with the tube awhile fluid under drawing pressure is being used to clean said tube.

The other arm 4 of the connecpart spaced from said outlet end of said tion 1 is preferably cast but may be other tube, said connection having means to engage said partand hold the connection in place while forcing fluid under pressure therethrough to clean the tube.

2. A tube cleaner comprising a connection adapted to be'remo'vably engaged with the outlet end of the tube, and a spring device for holding said connection in engagement With said tube, said connection having a passage for supplying fluid under pressure to the tube.

3. A structure as specified in claim 2, said passage opening in one direction, said spring device being carried by said connection and being self-projected in the other a direction until engaged With a fixed part spaced from the tube end.

4. A tube cleaner comprising an L-shaped connection having a fluid pressure passage and a spring device carried by said connection to engage a part spaced from the tube, said spring device being self-projectable beyond the outer side of said last named arm.
